Description

Technical Field

[0001] The present invention relates to the technical field of power equipment, and in particular to an intelligent switch device with remote approval and management functions and an intelligent switch system thereof. Background Art

[0002] During actual production in factories or workshops, on-site operators often violate regulations by using electricity or illegally pulling wires. This behavior can not only damage factory or workshop equipment but also cause personal accidents. Currently, most factories or workshops require that when electricity is needed, an application be submitted. The equipment management unit then dispatches personnel to verify the application and opens the power box door for the construction unit to use. After the use is complete, the user notifies the management unit and shuts down the power. This solution is cumbersome, difficult to manage, inefficient, and labor-intensive. Therefore, to address these issues, it is necessary to design an intelligent switch device and its associated intelligent switch system with remote approval and management capabilities.

[0003] The following are the relevant documents found on intelligent switchgear and intelligent switchgear systems with remote approval and management functions:

[0006] Patent 3: Construction Site Intelligent Power Distribution System; Application Number: 201710494020.2; Application Date: June 26, 2017; Applicant: Hebei Second Construction Engineering Co., Ltd.; Abstract: This invention discloses an intelligent power distribution system for construction sites, used for temporary power distribution control at construction sites. It includes a construction information management platform, as well as a main distribution cabinet, distribution boxes, and switch boxes, each containing an intelligent control box, inductors, and contactors. By leveraging automatic control and information technology, it addresses challenges such as the difficulty of managing and controlling temporary power distribution at construction sites, providing power safety alarms, maintaining equipment power consumption statistics, and shutting down equipment during idle periods. By combining the intelligent control box, main distribution cabinet, power control server, and construction information management platform, it enables real-time and accurate monitoring of the power consumption and status of each power distribution line, including the users, remote control of the power supply of each power-consuming device, and enabling card-based power access, device identification, real-time alarms and power outages for equipment overcurrent, overload, and overvoltage, as well as full Wi-Fi coverage at the construction site.

[0007] It can be seen from the above literature that most of the switch boxes currently used in factories or enterprises are manual switch boxes. When electricity is needed on site, the equipment management department needs to arrange personnel to go to the site for verification, open the box door and supply electricity for on-site use. After use, the user department will notify the management department to shut down the power and close the door. The use procedures are cumbersome, the management is difficult, the efficiency is low, and a lot of manpower is consumed. Although some factories or enterprises have configured remote-controlled switch boxes, the existing remote-controlled switch boxes still have shortcomings in actual use. Since the existing remote-controlled switch boxes lack a supporting intelligent switch system, the so-called remote control is highly dependent on having the control right of the remote-controlled switch box. If the on-site department wants to use the remote control switch box, it needs to call or send a message to the management department. After the management department agrees to the application, it will control the remote control switch box to power on. Compared with the switch box with pure manual power-on, it only saves the time for the management department to arrive at the site. In addition, this remote application process is not standardized, and the management department cannot obtain the identity of the applicant and cannot know the applicant's true intention of electricity use, which can easily cause safety accidents. At the same time, the existing remote control switch box has poor anti-interference ability when sending and receiving control signals, which can easily cause incorrect power-on or power-off, and does not have the function of uploading electricity consumption, resulting in the management department being unable to accurately understand the actual electricity consumption situation on site. Summary of the Invention

[0008] The purpose of the present invention is to solve the above problems and provide an intelligent switch device and an intelligent switch system with remote approval and management functions.

[0009] The intelligent switch device with remote approval and management functions includes: a box body, a box cover, a plastic connecting strip, a QR code nameplate, a stop indicator light, a run indicator light, a socket, an electric meter, a No. 1 circuit breaker, a control module, a contactor, a manual switch, a No. 2 circuit breaker, an antenna, a filter, a 4G module and a fuse. The box body and the box cover have the same side surface inside which several plastic connecting strips are fixed together by screws, and the outer edges of the box body and the box cover are provided with several threaded holes and connected by bolts. The QR code nameplate, the stop indicator light, the run indicator light and the socket are embedded in the box body. On the front of the cover, the electric meter, No. 1 circuit breaker, control module, contactor, No. 2 circuit breaker, antenna, filter and 4G module are installed inside the box, and the manual switch is embedded in the side of the box. The three-phase five-wire power supply runs through the box and is connected to the meter input terminal. The input terminal of No. 1 circuit breaker is respectively connected to the meter output terminal A, B, C three-phase and N line. The output terminal of No. 1 circuit breaker is connected in series with a fuse. The control module is provided with No. 1 terminal, No. 2 terminal, No. 3 terminal, No. 4 terminal, No. 5 terminal and No. 6 terminal. The contactor contains a coil, a normally open linkage contact, a normally open contact and a normally closed contact. The N line of the three-phase five-wire power supply is connected to the No. 1 circuit breaker outlet terminal with the No. 1 terminal and the No. 2 terminal of the control module respectively, and the normally open contact and normally closed contact of the contactor are connected in parallel between the N line of the three-phase five-wire power supply and the No. 1 circuit breaker outlet terminal. The normally open contact and normally closed contact are connected in series with the run indicator light and the stop indicator light respectively. The No. 3 terminal and the No. 4 terminal of the control module are connected, and the coil of the contactor is connected in series between the No. 3 and No. 4 terminals. The No. 5 terminal and the No. 6 terminal of the control module are connected, and the first contact of the normally open linkage contact of the contactor is connected in series between the No. 5 and No. 6 terminals. Manual The two ends of the switch are respectively connected to the No. 2 terminal and the No. 4 terminal of the control module. The incoming end of the second contact of the normally open linkage contact of the contactor is connected to the outgoing end of the No. 1 circuit breaker. The incoming end of the No. 2 circuit breaker is respectively connected to the outgoing end of the second contact of the normally open linkage contact of the contactor and the N line of the three-phase five-wire power supply. The incoming end of the socket is respectively connected to the outgoing end of the No. 2 circuit breaker, the remaining two phase lines of the meter outgoing end and the PE line. The antenna is electrically connected to the filter, the filter is electrically connected to the 4G module, the 4G module is electrically connected to the control module, and the meter is electrically connected to the input end of the control module.

[0010] Furthermore, the socket is an industrial socket.

[0011] Furthermore, the electric meter and the control module are connected via an RS-485 bus.

[0012] Furthermore, the control module is a single chip microcomputer.

[0013] Furthermore, the manual switch is a normally open manual switch with a mechanical lock structure.

[0014] In order to realize an intelligent switch device with remote approval and management functions, the intelligent switch system of the present invention includes: an embedded program, a host computer and a server. The host computer installed with the embedded program receives and displays the electricity application form sent by the intelligent switch device with remote approval and management functions, and sends a control signal to the intelligent switch device with remote approval and management functions. The server stores the electricity application form and electricity approval form of the host computer, and transmits the electricity application form and electricity approval form to the host computer.

[0015] Furthermore, the smart switch system is divided into three types of management permissions, namely system administrator, smart switch device administrator and ordinary users. The system administrator can manage the smart switch device and assign smart switch device administrator permissions. The smart switch device administrator can review the application for smart switch device and view the real-time status and usage records of the smart switch device under his charge. Ordinary users can initiate the use / return application of smart switch device and report faults of smart switch device without authorization.

[0016] Furthermore, the smart switch system has the function of online application submission and mobile application approval. After ordinary users scan the QR code on the on-site electrical box, they can open the WeChat applet, fill in the relevant information unit, name, telephone number, usage and termination time on the smart switch equipment information page, submit the use / return application, and choose to take photos and upload pictures, or online videos, etc. as attachments / basis for the application. When a fault is found in the smart switch equipment, a fault report can also be filled in. After the smart switch equipment fault report is reviewed and approved, the system automatically trips the faulty switch. After receiving the application reminder, the smart switch equipment administrator can verify the application, approve or reject the application operation. The administrator agrees to use it and clicks online to remotely operate the power supply and authorize use. If the smart switch equipment is used for more than a certain period of time, the system automatically pushes a message to the user and the smart switch equipment administrator, prompting the user to apply for an extension of the use time or perform a tripping operation, and prompting the smart switch equipment administrator to track the use of the smart switch equipment to prevent power loss or even accidents.

[0017] Furthermore, the smart switch system has a message reminder push function. Within the allowed number of messages, the associated public account pushes WeChat messages in real time. When the smart switch device administrator fails to process the message within the specified time, the system automatically triggers SMS and email push.

[0018] Working principle:

[0019] First, install the intelligent switch box, fix the box in a suitable position, then adjust the No. 1 and No. 2 circuit breakers to the circuit-breaking state, and then connect the lines. After completing the line connection, use plastic connecting strips and screws to connect the box body and the box cover into a whole, and then screw the bolts into each threaded hole, and then adjust the No. 1 and No. 2 circuit breakers to the circuit-passing state to complete the installation.

[0020] Then, build the intelligent switch system at a suitable location in the factory or enterprise, install the host computer and server, and debug the program. After the system is stable, enter the information of all the intelligent switch boxes on site into the intelligent switch system, and set up system administrators, intelligent switch equipment administrators and ordinary users.

[0021] When electricity is needed on site, ordinary users can scan the QR code on the on-site electrical box to open the WeChat applet, fill in the relevant information unit, name, phone number, use and termination time on the smart switch equipment information page, submit the use / return application, and choose to take a photo and upload a picture, or online video, etc. as an attachment / basis for the application. When a fault is found in the smart switch equipment, a fault report can also be filled in. After the fault report of the smart switch equipment is reviewed and approved, the system will automatically disconnect the faulty switch.

[0022] After ordinary users submit their applications, the associated official account will push WeChat information in real time. If the smart switch device administrator fails to process the message within the specified time, the system will automatically trigger SMS and email push. After receiving the application reminder, the smart switch device administrator can verify the application and approve or reject the application. If the administrator agrees to use it and clicks "Approve" online, power can be remotely supplied and authorized for use. If the smart switch device is used for more than a certain period of time, the system will automatically push messages to the user and the smart switch device administrator, prompting the user to apply for an extension of the use time or to perform a tripping operation, and prompting the smart switch device administrator to track the use of the smart switch device to prevent power loss or even accidents.

[0023] When the approval is passed, the terminal manager sends a power-on signal to the smart switch box. The power-on signal is picked up by the antenna with a filter. After filtering out irrelevant signals, the signal is transmitted to the control module through the 4G module. The control module controls the contactor to operate. At this time, the socket is turned on, and the on-site production personnel start each electrical equipment. During the power consumption process, the operation indicator light is turned on and is always on, and the electric meter and control module record the power consumption and power consumption duration respectively. The control module sends the collected power consumption and time information through the 4G module via the filter and antenna to the terminal. The terminal sends a signal in time according to the power consumption and time information to control the smart switch box to power off. After the power is off, the stop indicator light is turned on and is always on, while the operation indicator light is disconnected and extinguished.

[0024] In addition, when the control module controls the contactor to operate, it will verify whether the contactor operates normally through the normally open linkage contact and send relevant information to the terminal. If the contactor does not work normally, the terminal manager will be informed. At this time, the manager will come to the site and manually power on the device by controlling the manual switch with the key.

[0025] The significant beneficial effects of the present invention are:

[0026] (1) The present invention uses intelligent switching devices in conjunction with intelligent switching systems to realize functions such as remote approval of application / return of intelligent switching devices, remote management of intelligent switching devices, remote maintenance, viewing of opening and closing status, and data statistics, which can facilitate users and managers to apply for the use of intelligent switching devices and manage intelligent switching devices.

[0027] (2) The present invention adopts the method of scanning a QR code and filling in information to apply for electricity, which solves the low efficiency caused by the existing remote switch box requiring the applicant to notify the manager by phone or message to remotely power on. At the same time, the application method through the QR code is simple and standardized, which helps terminal management personnel to systematically understand the electricity usage situation on site.

[0028] (3) The present invention integrates an electric meter and connects the electric meter to the control module, so that the control module can obtain the specific power usage of the intelligent switch box in real time, and then send the power usage to the terminal through the 4G module, filter and antenna, so that the terminal can obtain the detailed power usage of the workshop or factory and facilitate the enterprise to make production adjustments.

[0029] (4) The present invention integrates a feedback circuit in the intelligent switch box, so that the terminal can obtain whether the intelligent switch box is powered on normally. When the control module fails, it can also be manually powered on through a manual switch, avoiding the impact of the intelligent switch equipment failure on the production plan and improving the fault tolerance of the intelligent switch equipment.

[0030] (5) The present invention uses a filter to enable the intelligent switch box to better filter irrelevant control signals, making the control of the intelligent switch box more precise, avoiding the intelligent switch box from being powered on incorrectly due to receiving control signals from other devices, avoiding safety hazards, and making the present application more suitable for the complex environment of factories or workshops.
